This is the employees table
and this is departments table
Now, the goal is i want the dropdown on edit page to display department name of the employee belongs to, while the dropdown still have all of the department name.
so i change can it, but when i run this code it gives me this error.
Trying to get property 'id' of non-object (View:
C:\xampp\htdocs\ims-it-laravel7\resources\views\employees\edit.blade.php)
i have read other threads here but those code still doesn't solve the problem

Answer 1

$departmentlists = Department::pluck('id', 'name');
Later You use
#foreach($departmentlists as $dl) and $dl->id
$dl is NOT an object, it is an array because of the pluck() function.
More precisely it looks like this
[
"abc" => 1
"xyz" => 2
"foo" => 3
]
Note: To see it Yourself try using dd($departmentlists) or dump($departmentlists)
Please see Laravel Eloquent Pluck
In this case You might want to use Department::select(['id', 'name'])->get() as it will return collection of objects with specified properties.
